CM COMMUNICATIONS
I
2
CM refers to the Master mode of the I
2
C protocol. See the I
2
C specification for proto-
col details. In this mode, the PICkit™ Serial Analyzer will master the I
2
C bus only. It will
not respond as a slave. The control block of memory dedicated to communication
allows for setting of the bit rate and displaying event markers in the software windows.
